Mari, in Syria, was one of the great cities of Mesopotamia. It was a trading center on the Euphrates River and was founded some 7,000 years ago. Archaeologists have discovered the giant palace of a Sumerian ruler, a temple to Ishtar, and a huge library with more than 25,000 clay tablets written in Akkadian cuneiform.

Now Popular Archaeology magazine reports that erosion and neglect are returning the city to the earth. The people of Mari built with fired mud brick, using clay that was cheap and plentiful along the banks of the Euphrates. Wind and rain have been picking away at the bricks for thousands of years, and it doesn’t help that more walls have been exposed by archaeologists. Dust to dust.

I visited Mari in the 1990s and it was one of the biggest archaeological orgasms of my life. To walk through a Mesopotamian palace, to visit one of the ancient world’s biggest libraries, and to stand atop a ziggurat all in the same afternoon is something you can’t do anywhere else outside of Iraq. It’s one of many outstanding archaeological treasures in Syria that are in desperate need of protection and conservation. Crac de Chevaliers, one of the ten toughest castles in the world, is also in danger.

Sadly, with the Syrian government more interested in killing their own people, I don’t think protecting the world’s heritage is very high on their “to do” list.
